LEONARD HENKLE, OEROOHESTER, ASSIGNOR TO THE INCAN- DESCENT GAS BURNERCOMPANY, OF NEW YORK, N. Y.

INCANDESCENT GAS-BURNER.

, SPECIFICATION forming part of Letters Patent No. 437,649, datedSeptember 30, 1890.

Application filed July 20, 188 9.

' To all whom it may concern;

:or thimble, in combination with a compound burner for burning gas andair, or in connection with 'an ordinary burner designed for thecombustion of fuel-gas, water-gas, or any other gaseous substancecapable of producing a high degree of heat by which the platinum cone orthimble can be maintained at a high degree of incandescence; also, tothe construction whereby atmospheric air is mingled with the gas inorder to produce more perfect combustion and a higher degree of heat;and it consists of the construction, arrangement, and

combination of parts disclosed in the following specification, referencebeing had to the accompanying drawings, which form a part thereof, andin which similar letters of reference indicate like or equivalent partswherever found throughout the several views, and

' in which Figure 1 represents a central vertical sectlon of my improvedburner; and Figs. 2, 3, 4,

:5, and 6 modifications in the construction and adaptation thereof, eachbeing in central vertical section.

Referring to Fig. 1, A indicates the burner, which is preferablycylindrical in form, and

B a tube, by which gas or gas and air is ad mitted thereto, tube B beingprovided at its lower end with a screw-threadedsocket, by means of whichthe burner may be attached to the ordinary gas-fixture.

As a means of mingling air with the gas the tubes H, which are connectedwith the tube B and communicate with the gas-passage therein, as shown,are provided. These tubes are extended upward and outward and areprovided at their upper outer ends with small projections or lugs h, andthe reflector N is provided with sockets n, which fit the projections h,whereby the reflector, which is sup Serial No. 318,136. (No model.)

ported by the air-tubes H, is retained in place. The reflector N isprovided at its outer edge with an upwardly-projecting rim or flange,which serves to retain in place the shade M,

which is supported by the reflector N, and which, with this improvement,serves in the I thereof.

The top of the burner is provided with a circle of small perforations orholes through which the gas escapes as in the ordinary burner, and thenumber of these perforations may be increased or diminished, as may befound necessary.

The operation is as follows: Gas enters the burner A through tube B, andair enters said tube and is mingled with the gas therein through thetubes H in the desired amount. The mingled gas and air is ignited as itescapes through the small perforations in the top of the burner. Themingling of the gas and air before ignition, produces, as in theordinary Bunsen burner, almost perfect combustion, and the additionalsupply of air to the gas as the same escapes from the burner addsmaterially to this effect. The result is a very high degree of heat withbut little if any visible flame. The platinum cone or 'thimble is atonce raised to a high degree of incandescence and remains inahighly-luminous condition as long as the burner is ignited.

By means of the perforated diaphragm D and the screw E the amount of gasadmitted to the burner may be regulated to any desired amount, and asimilar regulating device, or one like that shown in Fig. 6, may beapplied to the air-tubes H, whereby the amount of air mingled with thegas may also be regulated. If an air-regulator like that shown in Fig. 6be employed, the outer ends of the tubes must be closed.

The construction shown in Fig. 2 is similar to that in Fig. 1, with theexception that the I00 reflectorN is omitted and a ring provided with aflange O and sockets n is substituted as a support for the shade M,which in this case is shaped somewhat differently from that shown inFig. 1, in order to secure a draft when the reflector, with its centralopening, is not employed. also provided with perforations for the'escapeof the gas in its lower side instead of in its top, as in Fig. 1, andthe platinum cone or basket is supported from the top of the burner andextends down around the same. The gas or gas and air escapes from theburner through the perforations in its lower side, as shown by thearrows therein, and is met when ignited by an ascending current of air,as shown by the ascending arrows, and the flame is directed upwardaround the burner and between the same and the platinum cone, and 20 'ofincandescence, as in Fig. 1.

the latter is at once raised to a high degree It is evident that thereflector N may be used in connection with this form of construction, ifnecessary or desired. This construction is simpler and more economicalthan that shown in Fig. 1, and in many respects is preferable thereto.

In Fig. 3 is shown an ordinary Argand burner, which may be readilysubstituted for that shown in Fig. -1, and Fig. 5 represents a burnerwhich may be' employed in place of that shown in Fig. 2. This burner isdiflferent in form, being much broader in cross-section,.and the bottomis convex and provided over its entire surface with numerous smallperforations. The platinum coneis inverted and placed in position bysliding the same over the tube B, a central opening in the conebeingprovidedforthis purpose, andisretained in place by bending theupper edge over the burner, or in any other desired manner. The

operation is substantially the same as with and in Fig. 6 is shown aform of construction in which these tubes are omitted, air beingadmitted to the gas-passage by means of holes or openings B, the amountof air entering being regulated by a band K, provided with holes, whichmay be made to register with those in the tube B, the admission of airbe ing regulated by turning the band. In using this form ofconstruction, however, it will be necessary to provide a chimney orglobe in order to secure a draft.

It is evident that this burner may be inverted, if desired, and Fig. 4represents a burner in this position. The application of the air- Theburnerin this figure is tubes H or air-admitting construction shown inFig. 6 to this inverted burner will readily suggest itself to any oneskilled in this art.

This invention is not limited to the use of platinum wire as asubstancefrom which the cone or thimble H is made, as any substancesknown and used for such purposes may be substituted, nor is theinvention limited to the manner of forming the cone or thimble orsupporting the same. It is also evident that the construction of theair-tubes H may be modified and many other changes made in the formationof the various parts of the burner without departing from the scope ofthis invention.

Having fully described the invention, its construction, and application,I claim and desire to secure by Letters Patent the following:

1. The combination, with a burner, of a tube for supplying gas theretoand supporting the same, air-tubes communicating with the gassupply tubeand supported thereby, and a shade supported by said air-tubes,substantially as shown and described. 1

2. The combination of a gas-burner, a tube for supplying gas thereto andsupporting the same, air-tubes communicating with said gassupply tube,supported thereby, extending upward and outward, as shown and described,and a reflector supported by the said airtubes, substantially as and forthe purpose set tubes communicating with the gas-supplytube andsupported thereby, a platinum cone or thimble supported by the burner, areflector having a central opening over the cone or thimble, and ashade, also having-a central opening, the reflector and shade beingsupported by the air-tubes, substantiallyas shown and described.

4. The combination of a gas-burner, a tube for supplying gas thereto,air-tubes communicating with said gas-tube and supported thereby andextending upward and outward, a reflector provided with a centralopening supported by said air-tubes, and a shade provided with a centralopening over said reflector and supported thereon, substantially asshown and described.

5. The combination,with a gas-burner, of a tube for supplying gasthereto, air-tubes communicating with said gas-tube and supportedthereby, a reflector supported by the air-tubes, a platinum cone orthimble suspended over the burner, and a shade provided with a centralopening, also supported by the air-tubes, substantially as shown anddescribed.
